Patent CA-1338098-C (CA)
Inventor: ISOBE MITSUTOSHI
IPC: C21B5/00
Filed: 1988-08-31
Granted: 1996-03-05
Abstract: Disclosed herein is a method for operating blast furnace, wherein, when charging coke and ore alternately from the furnace top to form alternate coke and ore layers for operation of a blast furnace, a coke layer is formed by charging coke of properties especially suitable for improvement of gas and liquid permeability of the coke layer to the central part thereof or an ore layer is formed by charging ordinary versatile type coke to the central part of the ore layer prior to formation thereof.  The centrally charged coke forms a major part of the dead coke layer which is sequentially renewed under the cohesive zone of the blast furnace to maintain appropriate gas and liquid permeability of the dead coke layer, thereby enhancing the production efficiency and stability of the blast furnace operation while suppressing erosive wear of refractory walls of the furnace.

Title: Bubble-type cushioning and packaging sheet and method  of manufacture
Inventor: CHANG TED B
IPC: B65D81/03
Filed: 1989-01-13
Granted: 1995-08-08
Abstract: Bubble-type flexible cushioning and packaging sheets are formed using films which are composites of single extrusion  or multiple  extrusion polyethylene  films having  density,  molecular  weight  and,  optionally, additives selected to provide a desired combination of qualities including heat sealability and low gas/vapor transmission.   A  preferred  film  material  has  a cross-sectional profile consisting of an inner region of linear low density polyethylene material surrounded by  outer  regions  of  high  molecular  weight  medium density polyethylene material.  The material permits the    formation   of preferred,    square   bubble configurations using a process which involves sealing two such films along generally parallel longitudinal lines;  inflating the films between the longitudinal sealing lines; then sealing the films along transverse lines to form inflated rectangular pockets or bubbles therebetween.

Granted: 1993-07-13
Abstract: ABSTRACT OF THE DISCLOSURE          A display apparatus automatically rounds corners of a rectangular area frame for display thereof, the rectangular area frame including that of a window or that of a graph and the like displayed within the window.  The rounding is effected by automatically calculating and displaying the circular arcs (ellipstic arcs) of the corners based on the inputted corner coordinates of the rectangular area frame, or by not displaying one or several dots of each corner. In the case where multi-windows are displayed in an overlap manner or a plurality of rectangular area frames are displayed within a window, the corners are not displayed stiffly and emphasized unnecessarily, thus providing a visually soft and natural display image, improving the quality of displayed images, and providing an improved handy method for use by an operator.  In a document editing apparatus, the corners of a rectangular frame of a window or of a rectangular area for display of graphs or the like in the window are visually recognized round, whereas the corners of a hard copy are formed with original angles.

Abstract: ABSTRACT OF THE DISCLOSURE     A resonant scanning unit utilizes a "tuning fork" design with a mirror mounted on one arm of the tuning fork and a counterbalance mass mounted on the other arm.  A voice coil electromagnetic motor mounted between the arms causes the arms to move in opposite directions.  Light generated by a line of LEDs is reflected from the oscillating mirror to generate a raster display.  Reaction forces generated by the motions of the mirror and counterbalance mass cancel at the device base, reducing vibration.  In addition, the inventive structure allows placement of the mirror pivot point away from the center of the mirror which allows display devices constructed with the structure to be reduced in size.

Abstract: Abstract of the Disclosure A flour sifter for separating doubles from fine particulate matter in a breading mixture, comprises a hopper for receiving the breading mixture.  The lower portion of the hopper includes a sifting screen along most of the longitudinal length that is sized to allow only the fine particulate matter to pass therethrough.  A slot at one end of the hopper is large enough for the doughballs to pass therethrough.  The hopper further includes an auger brush having a helical pattern of bristles along the length of the brush.  The auger brush is removably rotationally mounted within the hopper such that said ends of the bristles rotate at least adjacent to the sifting screen.  A motor and coupling mechanism rotate the auger brush within the hopper, so that as the auger brush rotates, the helical pattern of bristles urges the doughballs toward the slot in the lower portion, while the fine particulate matter of the breading mixture falls through the sifting screen.   In one embodiment, the hopper is an insert for a sifter table that is removably mounted within a hopper insert enclosure.  The hopper insert is mounted to accommodate a breading lug above the insert.  The enclosure is provided with mounting flanges to support another breading lug below the hopper insert to receive the sifted fine particulate matter.  A doughball ejector chute is associated with the slot at one end of the hopper insert to direct the doughballs from the hopper insert to a doughball collector pan.

Abstract: The apparatus accepts dry stripped crude fiber such as straw or sugar cane wastes, coconut husks, or elephant grass, compacts them into a relatively dense sheet, and bonds a strong surfacing material such as a heavy paper to the faces and edges. The sheet, continuously flowing from the apparatus, is cut into standard lengths and the cut ends are capped with the same surfacing material. A precompactor near the end of an entrance chute into the apparatus uniformly predensifies the incoming fiber prior to its compaction by means of a ram. The ram is carried on roller bearings especially adapted to withstand the weight and other forces associated with the continuous movement of the ram. The compacted material is continuously propelled by the ram and enters a press, where heat and pressure produce a dimensionally stable sheet bonded together partially by natural resins released from the fibers by the heat, and partially by mechanical interlinking between fibers. In the following operation, the sheet is covered with the surfacing material, which is successively folded over and bonded to the edges of the sheet. The surfacing material, provided in discrete rolls, is continuously available from a feeder station, which facilitates the substitution of a fresh roll as the material is consumed. In the following sawing and end sealing operations, fully surfaced sheets of standard lengths are produced.
